Officials with the San Bernardino County Sheriff’s Department said deputies arrested a 24-year-old Rancho Cucamonga man on suspicion of lewd acts at apartment complexes and following a woman from her apartment complex gym to her apartment.

Ryan Bernard Oneal was arrested Tuesday, Dec. 4, on suspicion of lewd acts in public, stalking and attempted burglary, the Sheriff’s Department said in a statement. Deputies were first notified of an unknown man who was following a woman from her gym to her apartment on Nov. 30. Once at the apartment, authorities said he attempted to follow her inside.

“It is believed that the suspect was targeting the woman in an attempt to sexually assault her,” the Sheriff’s Department said. “The woman’s husband came out and confronted the suspect who left the scene. Deputies conducted an area check and were unable to locate him.”

Authorities said Oneal is suspected of visiting various gyms and pool areas at apartment complexes in Rancho Cucamonga, where they allege he masturbated in women’s restrooms.

Officials said deputies found Oneal in the same complex on Tuesday morning where they say he previously followed the woman.

“Based on the information obtained during the investigation, it is believed that Oneal may have followed or harassed other female subjects at the various apartment complexes in the City of Rancho Cucamonga,” the Sheriff’s Department said.
